'Supergirl' also hits a season high as it closes out The CW's superhero crossover.

NCIS and The Conners both improved in adults 18-49 Tuesday, with the latter tying The Voice for No. 1 in the demographic.

NCIS had week-to-week gains in both adults 18-49 (1.3, +0.1) and total viewers (12.15 million, up about 100,000). FBI held at 1.0 in the demo, but NCIS: New Orleans slipped a tenth of a point to 0.8.

A Tuesday edition of Supergirl closed out The CW's "Elseworlds" crossover with a season-high 0.7 in the demo and 2.13 million viewers (versus same-day averages of 0.4 and 1.26 million). As with Arrow on Monday, Supergirl had its best outing since the 2017 crossover. Black Lightning (0.4 in 18-49) also improved.

The Voice matched last week's 1.4, which also ties its season low. Special Darci Lynne: My Hometown Christmas followed with a 0.8, and Hollywood Game Night posted a 0.5. Fox aired reruns of The Gifted and Lethal Weapon.
